TITLE: GCN CIRCULAR NUMBER: 19010 SUBJECT: GRB 160131A: second epoch observations with the GMRT DATE: 16/02/11 10:00:38 GMT FROM: Poonam Chandra at TIFR Poonam Chandra (NCRA-TIFR) and A. J. Nayana (NCRA-TIFR) report on behalf of a larger collaboration: We reobserved GRB 160131A (GCN Circ. 18951) with the Giant Metrewave Radio Telescope (GMRT) at 1420 MHz band on 2016 Feb 10.78 UT. While we do not detect the GRB radio afterglow, we place very constraining 3-sigma upper limit on the GRB flux in the Swift error cicle (GCN Circ. 18970) to be 105 uJy. The GMRT data for GRB 160131A is public for anyone to use. Further observations are planned. We thank GMRT staff for making these observations possible. -- _________________________________________ Poonam Chandra National Centre for Radio Astrophysics Tata Institute of Fundamental Research Pune University Campus, Ganeshkhind Pune 411007, Maharashtra, INDIA Phone: +91 20 2571 9290 Fax: +91 20 2569 7257 Email: poonam@ncra.tifr.res.in Web: www.ncra.tifr.res.in:8081/~poonam/ _________________________________________
